Answer:
Slaves.
Step-by-step explanation:
The above-mentioned quotation was taken from the ruling of the Dred Scott v. Sandford case also popularly known as The Dred Scott case of 1857. Chief Justice Roger B. Taney upheld the decision outlining the majority court's view against the slave named Dred Scott. Taney's opinion defined the legal defense of the most extreme pro-slavery position. This decision of the Supreme court outraged the abolitionists, brought the anti-slavery movement impetus, and provided as a stepping stone to the Civil War.
